Hi,
welcome back, I was away for about 15 years and with the kids gone and retired I got back in. did not sell anything, glad I did not nice to have all that stuff.
I started out getting 2.4 radio , that was 6 years ago best thing I did . replace all the RX battery's with A123 with a charger for them, they will take a "life charger" They will last a lot longer.
sticks
good luck
